Former Rep. Ann Marie Buerkle, R-N.Y., announced on Wednesday that she will not seek a rematch with her two-time rival, Rep. Dan Maffei, D-N.Y.

"Serving the people of Upstate New York in Congress has been one of the highest honors of my life," Buerkle wrote in a morning email to supporters. "While I love Upstate New York and will always remain deeply committed to the people who live here, I have decided that I will not seek election to Congress in 2014."

But a federal judge redrew the state's lines following the decennial redistricting process, making the district more favorable for Democrats. In a 2012 rematch, Maffei defeated Buerkle 49 percent to 43 percent. Meanwhile, President Obama carried the district with 57 percent.

"Since departing office, I realize that I can be an effective advocate on issues from outside of Congress," she wrote. "Whether it is through my role as a Commissioner at the Consumer Product Safety Commission or as a politically engaged citizen, rest assured, I will continue to be active in the public arena, working toward ideals that will create a better, stronger America."
